Red Hat's Chris Kloiber has published a small script which create a DVD ISO from the Fedora CD ISOs

Roll your own DVD isos using my script. Get the latest CD isos into one directory, then run:

# mkdvdiso.sh /path/to/the/cd/isos /location/and/name/of/dvd.iso

# growisofs -Z /dev/scd0=/location/and/name/of/dvd.iso
